CR, or Caloric Restriction, is a dietary regimen that involves reducing calorie intake without compromising essential nutrients. Research has shown that CR can lead to various health benefits, including improved metabolic health, increased lifespan, and reduced risk of chronic diseases. It is often studied in the context of aging and longevity. CR can be practiced in different ways, such as intermittent fasting or simply eating smaller portions. While it may not be suitable for everyone, many people adopt CR to enhance their overall well-being and maintain a healthy weight. Always consult a healthcare professional before making significant dietary changes.
